摘要:
The invention relates to a method and device for bending superposed sheets of glass, comprising the sheets being picked up by a top form furnished with suction means creating an upward airflow blowing over the rim of the sheets, said suction being sufficient to lift and hold the superposed sheets against said top form, then the pressing of the sheets between the top form and a full surface solid concave bottom form furnished with openings, said pressing beginning while the suction of the preceding step is not yet finished or is finishing, then the forming of the superposed sheets, by suction of the main face of the bottom sheet through the openings of the bottom concave mold, said forming by suction beginning while the pressing is not yet finished, then the cooling of the sheets. Windshields free of optical defects may thus be produced.
摘要:
A process and system for bending glass sheets heated to their softening point. The glass sheets are laid on a concave bending frame and prebent by gravity. The prebent glass sheets are transferred to a transfer former with a concave forming surface, the transfer former being moved up through the concave bending frame, the perimeter of which is larger, and thus picking up the glass sheets. The transfer former is positioned so that in vertical projection it overlies a final bending former in the form of a frame with a concave forming surface. The transfer former is moved up through the larger-diameter final bending former, the glass sheets being laid on the final bending former. The glass sheets are bent into their final shape, and at the end of the bending operation, the glass sheets in their final shape are transferred from the final bending former to a transport system and cooled.

A curved, transparent laminated glazing is made of at least two fixed panes and of a multilayer laminate placed between them. The laminate includes at least one support film provided with a thin layer and with external adhesive layers, as well as with a marginal strip of an opaque material for delimiting the viewing area of the laminated glazing on at least one side. The support film, which extends over the viewing area, is cut to size according to the invention in such a way that its cut edge is still just covered by the marginal strip at least in a direction of viewing in transmission.

摘要:
A laminated glazing, containing an assembly containing at least two transparent sheets of inorganic glass or of a strong organic material, joined together by an interlayer of a thermoformable material or by a multilayer foil containing the interlayer. The interlayer comprises an alkyl hydroxyterephthalate luminophore material and an antioxidant additive. The laminated glazing is suitable for information display of the automobile windshield or architectural glazing type.
摘要:
The present invention relates to a laminated glazing for information display, of the automobile windshield or architectural glazing type, comprising an assembly of at least two transparent sheets of inorganic glass or of a strong organic material, joined together by an interlayer of a thermoformable material or by multilayer foils incorporating such an interlayer, said glazing being characterized in that a luminophore material of the hydroxyterephthalate type, combined with an antioxidant additive, is integrated into said interlayer, allowing said display.The invention also relates to a device for displaying an image on transparent glazing, comprising laminated glazing of the above type and a source generating concentrated UV radiation of the laser type, the radiation of which is between 350 and 410 nm, the UV radiation being directed onto the area or areas of the glazing comprising the terephthalate-type luminophore layer.
